This section describes the object life cycle management method that sets objects to be automatically deleted at a desired time. You can set the life cycle using the X-Delete-At or X-Delete-After headers in an object PUT (upload) request or POST request after upload. Even if you request and set the X-Delete-After header, it is converted to X-Delete-At and saved. To unset the lifecycle, use the X-Remove-Delete-At or X-Remove-Delete-After headers.
| Name | Application location | Type | Description |
|---|---|---|---|
| X-Delete-At | header | integer | Enter the deletion time of the object (Unix Epoch timestamp) |
| X-Delete-After | header | integer | Delete the object after the entered time (seconds) |
Note
Life cycles can be applied on a per-object basis. If the object to set the life cycle thereof is uploaded to DLO or SLO, you must set the life cycle of the segment object and manifest object respectively.
Caution
Objects deleted by life cycle settings cannot be recovered.
Set object life cycle (PUT)
An example of setting the life cycle by including the X-Delete-At or X-Delete-After header in the object upload (PUT) request is as follows:
Syntax
PUT /v1/AUTH_{project_id}/{container}/{object}
Request examples
curl -i -X PUT -H "X-Delete-At: 1540520319" -H "X-Auth-Token: $token" -T "/FILE_PATH/OBJECT" https://kr.archive.ncloudstorage.com/v1/AUTH_{project_id}/{container}/{object}
or
curl -i -X PUT -H "X-Delete-After: 3600" -H "X-Auth-Token: $token" -T "/FILE_PATH/OBJECT" https://kr.archive.ncloudstorage.com/v1/AUTH_{project_id}/{container}/{object}
Set object life cycle (POST)
An example of setting the life cycle by including the X-Delete-At or X-Delete-After header in the object POST request is as follows:
Syntax
POST /v1/AUTH_{project_id}/{container}/{object}
Request examples
curl -i -X POST -H "X-Delete-At: 1540520319" -H "X-Auth-Token: $token" https://kr.archive.ncloudstorage.com/v1/AUTH_{project_id}/{container}/{object}
or
curl -i -X POST -H "X-Delete-After: 3600" -H "X-Auth-Token: $token" https://kr.archive.ncloudstorage.com/v1/AUTH_{project_id}/{container}/{object}
View object life cycle
Here's an example of how you can view the life cycle set for an object.

Request examples
curl -i -X HEAD -H "X-Auth-Token: $token" https://kr.archive.ncloudstorage.com/v1/AUTH_{project_id}/{container}/{object}

Release object life cycle
You can release the lifecycle using the X-Remove-Delete-At or X-Remove-Delete-After headers. Header values are not checked.
Here's an example of how you can cancel the life cycle set on an object.
Syntax
POST /v1/AUTH_{project_id}/{container}/{object}
Request examples
curl -i -X POST -H "X-Remove-Delete-At: 1540520319" -H "X-Auth-Token: $token" https://kr.archive.ncloudstorage.com/v1/AUTH_{project_id}/{container}/{object}
or
curl -i -X POST -H "X-Remove-Delete-After: 3600" -H "X-Auth-Token: $token" https://kr.archive.ncloudstorage.com/v1/AUTH_{project_id}/{container}/{object}
